Help with coco question?

[Dankdad64]

I was wanting to use these, in 3 gallon fabric pots with 100 percent canna coco.. This is first time using coco. I was wondering if these blumats will provide enough run off to do what run off is supposed to do.Thanks for any help.

I havent done it myself,but if you look up the pinky sour grow in the growlog section,this guy does. And he's loving it.
Theres a few grows on here like that,you just gotta sift through the debris.

You get zero runoff with blumats.
